Seals, the early years

It’s the moment you’ve all been waiting for… stem-pinnipeds at Tet Zoo. Or, probable stem-pinnipeds anyway. This minimum-effort post is brought to you on the back of work showing that pinnipeds (seals, sea lions and walruses) are monophyletic, not diphyletic, and that the taxa shown here – Potamotherium, Puijila and so on – really are [...]

A brief history of muskrats

A brief history of muskrats

Earlier in the year I made a promise that I'd get through more rodents here at Tet Zoo. Rodents, you see, divide people like no other group of tetrapods.

The 6-ton Blue whale model at London’s Natural History Museum

A series of meetings meant that I found myself in London’s Natural History Museum yesterday, and with my friends and Tet Zoo supporters Dan and Felix Bridel (great t-shirt, Felix) I spent a while gawping at the always fascinating life-sized Blue whale Balaenoptera musculus model that hangs in the Mammal Hall.

Reasons for really liking wildebeest

There are lots of reasons for liking wildebeest… or gnus. For me, the main one comes from the fact that they are insanely flamboyant in appearance.

Some of The Things I Have Gotten Wrong

As a regular reader, you might know that Tet Zoo has been going for over nine years now. I've written about a lot of stuff, I’ve been intrigued and enthused by a substantial number of animals and animal-themed topics, and I’ve been attracted to a variety of controversial ideas and claimed discoveries.

Domestic Horses of Africa

I've said on several previous occasions that domestic animals are far from outside the Tet Zoo remit. On the contrary, I find them to be of great interest, and I think that their diversity, evolution and behaviour is something that we should pay attention to more often.

The Turcana and Other Valachians

I'm about as interested in domestic animals as I am in non-domesticated ones. Sheep of various kinds have been discussed on Tet Zoo a few times, and right now I want to say a few brief things about a breed I recently saw on several occasions in Romania - the Turcana or Tsurcana, a highly [...]

The Tet Zoo Guide to Gazelle Camels

Some of you will know that I'm putting together a giant textbook on the vertebrate fossil record… and, oh god, it isn't easy. If you want sneak-peeks on how things are going, please consider supporting me at my patreon page.

Confrontational behaviour and bipedality in deer

Confrontational behaviour and bipedality in deer

I've said it before and I'll say it again: one of the most familiar and frequently encountered of mammal groups (at least, to those of us in Eurasia and parts of the Americas) - DEER - are weird and fascinating when you get to know them.

The remarkable life appearance of the Woolly rhino

The remarkable life appearance of the Woolly rhino

One of the Pleistocene mammals depicted without fail in popular books – encyclopedias of prehistoric life and the like – is the Woolly rhinoceros Coelodonta antiquitatis (the species name is written antiquus in many sources).

Tapir attacks past, present, but hopefully not future

Last Thursday (August 8th, 2013) a Brazilian or Lowland tapir Tapirus terrestris at Dublin Zoo (Ireland) seriously attacked and injured a two-year-old girl that, believe it or don’t, was taken into the tapir’s enclosure.

A lynx, shot dead in England in c. 1903

For over 100 years, a potentially significant dead cat has been sat in storage in a British museum. Specifically, the specimen – the lynx Ab4458 – has been at Bristol Museum and Art Gallery ever since it was added to the collections there in February 1903, and what makes it significant is that it was shot dead after living wild in Devon, southern England. As revealed in a new paper published by Aberystwyth* University’s Max Blake and a team of colleagues (myself, Greger Larson, Charlotte King, Geoff Nowell, Manabu Sakamoto and Ross Barnett), the specimen represents a historic ‘British big cat’, though with ‘big cat’ being used very much in the vernacular sense, not the technical one (Blake et al. 2013).

Meet the Scaly-Tail Gliders

Among the weirdest and most fascinating of rodents are the scalytails/scaly-tails, scaly-tailed squirrels or anomalures, properly termed Anomaluridae.

Piltdown Man and the Dualist Contention

One of the most fascinating episodes in the history of palaeontology is that of Piltdown man, an alleged human ancestor discovered in 1908 at Piltdown in Sussex, England. Formally named Eoanthropus dawsoni in 1912, Piltdown man matched early 20th century expectations of what a human ancestor might be like. It combined a large brain with an ape-like jaw (therefore confirming ideas that the evolution of big brains led the way in hominin evolution), and it lived in Europe (confirming ideas that hominin evolution was a Eurasian event, the hominins of Africa and tropical Asia being divergent irrelevancies or side-branches). The African australopithecines had yet to be discovered, nor had scarcely any of the wealth of fossil African hominins we know of today.
